New Scope Demoboard from Batronix

[tv84]

I think I have an unfair advantage since the manual uses the MXO4 in most of its examples

I also thought about that. We forgive if you compensate us by comparing with one of "your own" boards.

I'll see how many more I have left

But actually this presents an interesting opportunity to compare oscilloscopes by testing them all against the exact same DUT:  not something that happens very often.

Oh yeah, it´s getting more and more better..

Glad to see I'm not the only person who thinks this is going to be a lot of fun ....

Damn you, Martin, you are typhoid Mary of demo boards...

 

Martin is a Batronix salesman!

If I had enough time, I could "feed" some models with the board:

Lecroy WS9054, HDO6034A, WS3024Z.
Siglent SDS1104X-E, SDS2104Xplus, SDS2504 plus HD and the two portable ones.
Rigol DS1054Z and so on...

I have to say again how much I like the documentation.  I have quite a few books on oscilloscopes (including a few in German), and it's refreshing to see something written (a) for beginners and (b) in a conversational, practical style. 

I particularly liked "Messerlebnis" - I'm going to have to find ways of working that word into conversations

[Martin72]

Ah, Bernstein..
I have the other one and was a little bit disappointed from the content.
More I like the short tek "book" about scopes.

[pdenisowski]

Working through the exercises in order - so far, very straightforward and signals are exactly as described.   I'm using a small screwdriver to (carefully) turn the knobs instead of using my fingers.  I like that they have a nice positive "click" at each position.

I also noticed that they labeled the flooded ground point a "Crocodile area"    (Note that the German for alligator clip is "Krokoklemme," so this makes perfect sense to me)
 
There might be one small typo:  in section 2.4.5 it says "Messen Sie das „SPI SCL“ Signal mit einem Tastkopf." (Measure the SPI SCL with a probe).

I think they meant I2C.  The SPI pin is labeled "SCK" and is idling low.  The I2C SCL signal is idling high looks exactly like the one in the manual.

[pdenisowski]

Was working on 2.4.7 (Window trigger) and got something that looked more like a differential CAN signal than the screenshot in the manual.  Then I realized I was plugged into the wrong BNC connector

Probably worth noting that if you're working straight through the manual, you should make sure the connector hasn't changed since the last exercise  

Edit: this was very clearly stated by Batronix, I just wasn't reading the instructions

[Martin72]

Ah, the slew rate trigger, on this I stopped yesterday...Must try it again.

[Martin72]

Must try it again

OK, I was a little bit confused...

When your first pic shows the right signalform, then I already got it right adjusted.
Because I stumbled over the screenshot (which is wrong titled, @Batronix) and over the sentence in the manual:

If your oscilloscope supports it, you can also set the slope trigger to
"Outside" and set the time range to 140 μs to 180 μs and to rising and falling edges.
 With this you should get all errors of this test signal triggered

This let me thought, it has to look like the screenshot (On top of that if you can see in the picture that the slewrate trigger was selected)....

[pdenisowski]

I worked through section 2.10 and everything has worked as expected.   A quick update:

1)  I like the fact that the runt trigger (2.4.8 ) example produces runts of different amplitudes

2)  The input coupling example (2.5) is also nice for showing how AC coupling allows you to see noise/ripple on a DC signal [see attached]

3)  Roll mode demo (2.6) was also helpful, since this can be hard to demo otherwise

4)  The noisy square wave to show the effect of averaging (2.7.1) is a nice demo.  I did however increase the number of average above the recommended 16 to get a more dramatic "cleaning up" of the signal [see attached]

5)  The peak detector (2.7.2) demo was also helpful, but here I did wish the manual explained why you see the double line

6)  And I always like a nice persistence demo (2.10)   The "intermittent" signal that shows up when persistence is enabled could also be used for some advanced triggering exercises and/or as a way to demonstrate the effect of acquisition rate (how long until you see the signal?)   I'll probably experiment with this more later.  [see attached]

My plan is to skip ahead and do all the serial decode examples next, since I did videos on most of these already   I'm intentionally saving FFT for last, since this is also a challenging thing to demonstrate.

Am I happy with it so far?  Yes, very

Grrr now I have to wait for it to come while watching other kids play...

Sorry - I need to go through the entire demo guide as quickly as possible so I can get back to what I was working on before Martin72 derailed me (danke, Kumpel )

I have five new YouTube videos sitting in my post-production queue (including, of all things, "Getting Started with MXO Series Oscilloscopes - Triggering Fundamentals") and I need to get them over to our social media team sooner than later.

4)  The noisy square wave to show the effect of averaging (2.7.1) is a nice demo.  I did however increase the number of average above the recommended 16 to get a more dramatic "cleaning up" of the signal

Checked this on my HD, with 64 averaging and took this as REF A.
Nice thing I didn´t noticed so far:
If you change the color of the REF trace, the hardware REF button will change it´s color too...Cool.

I was looking for an oscilloscope demo board as well. I could not decide on one of the Rigol or Siglent options yet, mainly because of the price point of more than 200 €. And why yet another toy? So, I decided to bury the plan.
This thread brought the wish back to life. Thank You Martin 
Waiting for UPS...

[Martin72]

Thank You Martin   

 

You´re welcome...
But my thoughts were exactly like yours - Why, why, why...
I already got a (good) demoboard..But I couldn´t resist and now it´s here.
So far without regrets.
Men and (technical)toys...

I will report this thread so that Dave can close ASAP... 

Even I surfed Batronix...     Stay away from the light...... 

[pdenisowski]

I will report this thread so that Dave can close ASAP... 

I wonder if Dave would be interested in doing a "demo boards" video - seems like a topic that would generate a lot of interest

Batronix has already updated the manual

I also reached out to them via email with a (different) question and got a very quick and helpful response, so bonus points for good customer support

[RAPo]

This forum is expensive, another one waiting for the postman.

[tv84]

Can you wildly guess what I just did?

Lololol!!!! 

[Martin72]

Today at work, the board with the lecroy HDO6034A together..
Playing with all the trigger stuff and it took me a while to realize that the persistence mode was active in some screenshots in the manual.
Could be mentioned in an update in the text...
Now I am curious about the decoder signals, the data packets are of different sizes and batronix has solved this very nicely:
The countries of Europe are named and their capitals in addition....

[KungFuJosh]

The Martin72 bug hit me this morning and I also ordered one. I hope Batronix gives him a commission for all these sales.
